Managed Bean (MBean)

What is managed bean (MBean)?
A managed bean (MBean) is a reusable software component for Java that represents a manageable resource, including components, applications, or devices. It is part of the Java administrative extension and is used to set applications, collect statistics, and notify events.
An MBean is a fundamental entity of Java Management Extensions (JMX). MBeans have an interface and a class. A standard MBean is defined via a Java interface. An MBean interface takes the name of the Java class it implements, appended by an MBean. This interface contains named and typed attributes that are readable and also writable. User code does not implement the interface.
